The present study was performed to evaluate the effects of xylazine and tiletamine + zolazepam on echocardiograms before and after experimental myocardial infarctions in clinically normal dogs taken preliminary examinations related to cardiac function. The results are as follows. With xylazine administration, left ventricle end-diastolic dimension, left ventricle end-systolic dimension, left atrium/aorta, ejection time and velocity of circumferential fiber shortening increased and mitral valve CD slope, % delta D decreased(p<0.01). In tiletamine+zolazepam administered group, interventricular septum amplitude(p<0.01), mitral valve DE slope(p<0.05) and ejection time(p<0.01) decreased and left atrium/aorta, ejection time also decreased compared with xylazine group(p<0.01). In 48 hours after experimental myocardial infarction group, anterior aortic wall amplitude decreased compared with control, xylazine, tiletamine + zolazepam group, respectively(p<0.01). Posterior aortic wall amplitude decreased compared with control(p<0.01). Left ventricle end systolic dimension increased compared with control and tiletamine + zolazepam group, respectively(p<0.01). Left ventricular posterior wall end systolic dimension decreased compared with control(p<0.01). Left ventricular posterior wall amplitude decreased compared with control and tiletamine+zolazepam group(p<0.01). Left atrium/aorta decreased compared with xylazine group(p<0.01). % thickening left ventricular posterior wall decreased compared with control(p<0.05). % delta D decreased compared with control and tiletamine+zolazepam group(p<0.01). Ejection time decreased compared with xylazine(p<0.01). Velocity of circumferential fiber shortening increased compared with control and tiletamine + zolazepam group(p<0.01). With xylazine administration 48 hours after experimental myocardial infarction, anterior aortic wall amplitude, posterior aortic wall amplitude decreased compared with control(p<0.01). Left ventricle end-diastolic dimension increased compared with control(p<0.01). Left ventricle end-systolic dimension increased compared with control and tiletamine + zolazepam group, respectively(p<0.01). Left ventricular posterior wall end-systolic dimension and left ventricular posterior wall end-diastolic dimension decreased compared with control(p<0.01). Left atrium/aorta decreased compared with xylazine group(p<0.01). % thickening left ventricular posterior. wall(p<0.05) and % delta D(p<0.01) decreased compared with control. Velocity of circumferential fiber shortening increased compared with tiletamine + zolazepam group(p<0.01). With tiletamine + zolazepam administration 48 hours after experimental myocardial infarction, anterior aortic wall amplitude decreased compared with control, xylazine and tiletamine+zolazepam group, respectively(p<0.01). Posterior aortic wall amplitude decreased compared with control(p<0.01). Left ventricle end-systolic dimension increased compared with control and tiletamine+zolazepam group(p<0.01). Left ventricular posterior wall end-systolic dimension, left ventricular posterior wall end-diastolic dimension and interventricular septum amplitude decreased compared with control(p<0.01). Left atrium/aorta decreased compared with xylazine group(p<0.01). % delta D decreased compared with control and tiletamine + zolazepam group(p<0.01). Ejection time decreased compared with xylazine group and velocity of circumferential fiber shortening increased compared withtiletamine+zolazepam group(p<0.01). Conclusively, echocardiography was proved to be a useful, diagnostic, non-invasive and simple method for establishing the diagnosis of myocardial infarction and evaluating the effects of drug on cardiac function before and after myocardial infarction.

화학적 보정약이 정상견의 도플러 심초음파에 미치는 영향
윤정희,Yoon, Jung-hee 대한수의학회 1998 大韓獸醫學會誌 Vol.38 No.2
Intracardiac velocities were determined and the wave-forms described for 4 flow areas of the normal canine heart following administration of chemical restraint drugs including xylazine HCl, ketamine HCl, and thiopental sodium using pulsed wave Doppler echocardiography. The result was that xylazine HCl and thiopental sodium reduced intracardiac flow velocities through mitral, tricuspid, aortic and pulmonary valves. It is also thought that precautions are required before using these drugs. Patterns of wave-forms had no changes between control and treatment groups. Doppler echocardiography allows the clinician to determine flow velocities across the different valves and within the various chambers of the heart. It is shown that establishing normal values and those related to chemical restraint administrations and knowing what influences them should allow the clinician to non-invasively diagnose a variety of pathological cardiac conditions.

전 병상 1인실 구조인 중환자실에 근무하는 간호사의 경험
윤정희,신영미,신수진,홍은민,Youn, Jung Hee,Shin, Young Mi,Shin, Su Jin,Hong, Eun Min 한국중환자간호학회 2021 중환자간호학회지 Vol.14 No.3
Purpose : This study aims to provide basic data for effective nursing interventions and improvement of nurses' work by exploring their work experiences in single-room-structured intensive care units (ICU) through focus group interviews. Methods : Data were collected through two focus group discussions conducted from March to November 2020 with 13 ICU nurses. Interviews were audio-recorded and analyzed thematically by investigators. Results : Through content analysis, 15 sub-categories and 6 categories were formed. Two themes, "positive experiences patients care in an independent space" and "difficulties in nursing work according to space separation of patients" emerged. There are positive aspects of single-room-structured ICUs, but it was found that practicing nurses had difficulties and required specialized nursing competencies. Therefore, efforts to reduce the burden of nurses in single-room-structured ICUs are necessary. Conclusion : The limitation of this study is that it was conducted in a single hospital because single-room-structured intensive care units are uncommon in Korea. However, this study is of great significance as a basis for establishing guidelines on the efforts required from nurses, hospitals, and governments single-room-structured ICUs in the future.

This study was conducted to investigate the effect of human-derived urine on the middle-aged women`s skin. The samples of 3-7year-old boy`s urine that was aged for three days was used in freeze-drying after dialysis. The subjects were housewife in their 40-60s middleaged women; a group of 10 students were selected for the dialyzed after three days urine group (DAU) and the other group of 10 students for the control group, which have general characteristics similar to the experimental group. The experiment has been conducted for a total of 8 weeks. When it comes to skin test, before the experiment and 8 weeks later after the first test, I measured the skin amount of keratin, melanin index, erythema index, SCE (L*, a*, b*), pores, pigmentation and wrinkles aroud eyes. In the results of analysis, in the case of a control group were all increased or not changed. On the other hand, DAU group showed decrease in variation of amount of keratin 49%(p<0.05), melanin index 17%(p<0.01), erythema index 12%(p<0.001), SCE a*(redness) 10%(p<0.01), pores 25%(p<0.01), wrinkles aroud eyes 11%(p<0.05) and to increased SCE L*(lightness) 5%(p<0.01), SCE b*(yellowness) 11%(p<0.01). Consequently, judging from the changes in the DAU group, it was confirmed that the ingredient of aged urine is very effective in improving skin. The results of this research can be used to demonstrate the potentials of aged urine applicated cosmetics.

본고는 일본의 현대 섬유미술에서 나타나는 자연주의적 경향성을 분석하고 그 특성들이 질료와 표현의 측면에서 어떠한 방식으로 나타나는지를 다루고 있다. 한국의 미술도 자연주의를 그 원형으로 하고 있지만, 일본의 미술도 “자연에 대한 사랑”으로 특징지어질 만큼 자연미에 깊이 경도되어 왔다. 이는 단지 형식적인 면뿐만 아니라, 제작의 태도 및 과정, 그리고그 동기에 있어서도 나타나는 특징이다. 이러한 자연주의 경향은 일본의 현대 섬유미술에서 도 동일하게 나타난다. 현대의 일본 섬유미술이 제작방식, 미의식, 재료에 대한 감수성의 측면에서 일본 고유의 자연주의적 전통을 계승 발전시켜 오고 있다는 점에서 일본의 현대 섬유미술을 이해하기 위해서는 자연주의적 특성에 대한 분석이 필요하다. 연구자는 일본의 현대 섬유미술에서 나타나는 이 자연주의적 특성들이 일본의 고유한 자연관을 그 원형으로 하고 있다고 보고, 그러한 자연관이 어떻게 섬유미술에서 나타나는지 그 연관성을 살피고자 한다. 일본의 자연관은 크게 두 가지로 설명될 수 있다. 비가시적인 것(신 내지 정령)과 가시적 자연의 상호연관, 자연과 반자연의 긴장 내지는 “자연스런 반자연”이 그것들이다. 자연관에 나타나는 이 두 특성은 현대 일본의 섬유미술에서 적어도 세 가지의 특성적 요소들로서 나타난다고 해석될 수 있을 것이다. 질료의 고유한 잠재성을 극대화시키려는 경향, 자연적과정의 우연성을 용인한 결과로 나타나는 패턴의 비결정적이고 불규칙한 규칙성, 비가시성의 현전 방식으로서의 투명성의 특성들이 그것인데, 본고에서 이 세 특성들은 여러 작품들에서 예증될 것이다. This Thesis has a purpose to deal with an analysis of the properties of naturalism in japanese contemporary textile arts, and the way how that characteristics come to being. Naturalism has been considered as the stylistic archetype of korean traditional arts, and the same to Japanese arts. Seeing that Japanese art are said to be marked by “love for nature”, they have a big affinity with beauty of nature. This is a characteristic presented not only in the light of form but also an attitude and process of making, and its intention. These properties of naturalism are the same as in contemporary japanese textiles. it is necessary to analyze their naturalistic properties as to understand contemporary textiles in that japanese own traditions of naturalism have been inherited to contemporary textiles. Conceived that japanese view of nature is deeply reflective in naturalistic elements presented in contemporary textiles, the relationship between japanese view or concept of nature and textile arts is being dealt with. Japanese view of nature can be explained in two ways. The one is the interconnection between the invisible(god or natural spirit) and the visible nature, the another is a tension between nature and anti-nature or the concept of “natural anti-nature”. And then, the interpretation as follows can be possible, that is, these two elements give birth to at least three properties of naturalism in contemporary japanese textiles : tendency of maximizing the potentiality of material itself, indeterminate irregular regularity of pattern caused by admitting natural casuality in work process, transparency expressing a way of presence of the invisible. These properties will be exemplified through various contemporary japanese textiles

Percutaneous needle aspiration biopsy is a reliable and useful procedure for diagnosing tumor with a low rate of complications and high diagnostic reliability. Subcutaneous malignant seeding of the needle tract is a well-known complication of percutaneous needle aspiration biopsy. Implantation metastases of the abdominal and chest walls have been reported after puncturing the tumor lesions of the liver, kidney, adrenal gland, lung and pleura. We report here on a case of subcutaneous seeding of hepatoid thymic carcinoma on the right upper back after a percutaneous needle aspiration biopsy. (Korean J Dermatol 2010;48(12):1104∼1107)
